Rubb shelter provides added security

 

Rubb environmental structures are helping to play a part in high profile nuclear decommissioning projects carried out by specialist management contractor Magnox.

 


 

Rubb Buildings Ltd worked with main contractor Costain to provide a 6m span x 6m long security containment shelter at the Magnox Bradwell treatment facility. The site is due to enter a 100-year ‘care and maintenance’ period in 2015.

 

The BVR structure features a galvanized steel frame with 3m high sidewalls. It is clad with a durable PVC membrane providing grey walls and a white roof. Access is via a 3m wide x 2m high roller shutter door in the front gable end of the building and a personnel door to the rear. It houses three tanks/generators and a sensor to detect any leakage within the facility. If this is activated the facility would shut down. The Rubb building accommodates existing pipework and includes two snoods and louvres on each sidewall for ventilation processes.

 

Magnox, owned by EnergySolutions, is the operations and management organisation which is responsible for ten nuclear sites and one hydroelectric plant in the UK. Magnox works for the sites’ owner, the Nuclear Decommissioning Authority on projects such as electricity generation, defuelling sites at the end of generation and decommissioning and clean-up.

 

The Bradwell site in Southminster is near to the Essex coastline. Electricity generation began in 1962 and ended in 2002. The site is following an accelerated decommissioning programme and is set to become the first reactor site in the UK to enter ‘Care and Maintenance’ in 2015.

 

The Magnox Care and Maintenance (C&M) preparations phase focuses on decommissioning and deplanting buildings and retrieving, treating and processing any waste in order to ready the site for C&M. This phase also ensures that any waste is moved to modern stores which are maintained. The types of buildings that will remain on site typically include reactor safestores, intermediate level waste stores or interim storage facilities.

 

Rubb Buildings Ltd has previously custom designed an emergency equipment storage facility for Magnox in Wales to meet new guidelines issued by the HSE. Sales Executive Grant Davidson said: “Rubb Buildings Ltd has worked on the vast majority of Magnox sites over the years and continue to do so. We pride ourselves on delivering bespoke building solutions for a variety of high profile clients that require robust flexible structures for their challenging environments."
